In previous COD games the DLC maps were always playable in the standard game modes automatically, but in ghosts only playable in the Onslaught playlists. Which means you are limited to only those maps and can't just choose TDM alone. This is extremely annoying and now i feel i have wasted my money on this DLC.

Previous COD games have had a pattern of offering a specific playlist option for a map pack right after it releases, and removing the previous map pack playlist, so it is likely this game will follow the same pattern. However, we cannot claim with any certainty what playlists will be in the future, since they are subject to change at any time.
